ADJUSTABLE REACTION RESISTANCE.

Application filed January 24, 1925, Serial No. 4,430. Renewed May 25,1927.

An object ofthis invention is to provide a simple and effective means for preventing a core from sticking or chattering when it is actuated to make or break a magnetic circuit.

brilliancy of an electrical current passing through a coil; and which also can he actu ated to graduallyj diminislrthe magnetic field oi force when the core is actuated to break thefield.

An object of the invention is to provide an adjustable reaction resistance that is simple in construction; durable in use, and which is easy to install in any suitable electric lighting system. a Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

The accompanying drawing illustrates the invention.

Fig. 12 is an in 'Figll.

Fig. 13 is a section on line m Fig. 12. Fig. 14 is a fragmentlal bottom'view of 2.

end view of the casing shown bolts 41; and the sheets and plates areprovided with upward extensions that when assembled form the magnetic poles 5, ;6 between which is secured the bottom portion of-acoil7.

I The coil 7 iswound to form. a central opening through which a core 8 is adapted to extend and be reciprocated on the ends of the poles 5, 6. V i v The core 8 isformed of metal ,sheets 9 that are secured together by rivets 10, 11; and the sheets 9 are :arranged to lie edgewise and in the same plane as the sheets 2.

A rod 12 ispivotally connected to the rivet 11 to facilitate a reciprocation of the core.

To prevent the core 8 from chattering or I sticking as it is moved toward or from the pole 5, a non-magnetic filler 13 is attached to the bottom edge of the free end .of the core; and a similar non-magnetic filler 14. issecured to the top edge of the pole 5 ad jacent the coil 7 and these fillers are constructed and arranged so that as the core 8 is moved onto or off of the pole 5 that the magnetic force is gradually increased to its full power or diminished until the force is negligible so that the core 8 can be moved toward or from the pole 5 without theusual sticking or chattering now common in adjustable reaction resistance-when ;the .magnetic circuit is broken.

In other words the metal sheets at'the bottom edge of the free end of the core, and

also the metal sheetsat the top edge of the pole 5. adja'cent the coil 7 are cut away to form SZLW tOOthBd recesses that are filled with non-inagnetic fillers 13, 14 cm are arranged to gradually increase or diminish the magnetic force of the resistance as they meet or separate.

In Fig. 5 the freeend of the core" 8 is shown 'beveled toapoint to thereby reduce the magnetic forecast-he coreis moved toward or from'the pole 5.

iii)

In iiig. let; the free end of the core 8 is tapered and also provided with a llUll l'l'lllnetic tiller for the purpose of preventing; stickingor chattering the case is moved toward or from the pole 5. i

It oesired the core 8 can be made to reciprocate in a non-inavnetic casing as ind'- catcd in Figs. 7, S 9, 11, 12 and 13.

As shown therein a casing 15 is provided with a base plate 16 that has its ends prorided with tongues 17 adapted to be fitted into grooves 18 that are cut into the metal sheets 2 of the body 1 to form tongue and grove joints between the plate 16 and the poles of the body 1, as best shown in i); so that when the casing 15 is fitted into place it extends through the coil 7 with the min-magnetic plate 16 arrangei witl. its top surface substantially level with the top of the poles 5, 6.

By this construction combination and arrangement of parts a resistance is provided in which the core can be reciprocated witlout it sticking or chattering; and also in which the side walls 19, 20 top 21 and the base plate 16 of the non-magnetic casing 15 for a guide for the reciprocation of the core 8.

It is understood, however that the nonmagnetic plate 16 can be separated from the guide casing; 15 it so desired. as indicated in Fig. 15.

In 10 the appliance is semi-diagrammatically shown in use. As seen therein the adjustable reactive resistance shown in a ho isina 22 that is tilled with an insulation 28 that surrounds all of the resistance except an OXtGlIQCCl end of the core and the rod ly which it i, adapted to be recipro cated.

The coil 7 is connected by wires 24-, 25 with terminals 26, 527 on the housing their terminals are in circuit with a 28 n as 22 and switch and laniip 29 by lighting; system wires 30.

31 so that as the resistance is manipulated to increase or decrease the lllfl lie'tlC torce the brilliancy oi the lamp 29 will be correspondingly increased or diminished.
